Public money deserves
public proof of savings
Councils and housing associations invest millions in energy efficiency. Taxpayers, auditors, and grant bodies all ask the same question: did it work? HeatFlow provides the measured, verified answer - building by building, pound by pound.
Accountability for every pound of public spend
Energy efficiency programmes in public buildings are funded by taxpayers, councils, and central government. The days of claiming savings based on consultant projections are ending. Auditors want measured data. HeatFlow delivers it.
Public Building Energy Tracking
Monitor gas, heat, water, and electricity consumption across council buildings, leisure centres, schools, and social housing. HeatFlow centralises all energy data into one platform with real-time visibility.
Prove Savings After Public Spend
When councils invest public money in energy efficiency, taxpayers and auditors expect proof. HeatFlow measures actual consumption reduction and generates reports that demonstrate value for money - not projections, verified data.
Grant Compliance Reporting
PSDS, SHDF, and local authority grants all require post-completion evidence. HeatFlow automates the reporting process - baseline data, measured savings, carbon reduction using BEIS factors - all in formats that funding bodies accept.
Multi-Stakeholder Visibility
Energy managers, finance teams, and elected members all need different views of the same data. HeatFlow provides role-based dashboards and customisable reports for each stakeholder group.
Portfolio Benchmarking
Compare energy performance across your building stock. Identify which buildings are underperforming, which retrofits have delivered best value, and where to prioritise next investment.
Net Zero Progress Tracking
Most local authorities have declared climate emergencies and set net zero targets. HeatFlow tracks your portfolio's total carbon emissions and reduction trajectory - showing whether you're on track to meet commitments.
Use cases for public sector energy managers
Council housing retrofit programme
A London borough invested £3M in boiler upgrades and insulation across 12 social housing blocks. They need to demonstrate to DLUHC that the works delivered the projected 25% gas reduction. HeatFlow tracks actual consumption at each building and generates quarterly progress reports with verified savings data.
Leisure centre decarbonisation
A leisure trust received PSDS funding to upgrade heating at three facilities. The grant conditions require annual reporting of energy and carbon savings for five years. HeatFlow provides continuous monitoring and automated annual reports with BEIS-compliant carbon calculations.
School energy programme
A multi-academy trust wants to reduce heating costs across 15 schools while meeting their published sustainability targets. HeatFlow benchmarks each school, identifies the highest-waste buildings, and tracks the impact of improvements - giving governors clear evidence of progress.
Frequently Asked Questions
How do councils prove energy savings after a retrofit programme?
By measuring actual consumption before and after works. HeatFlow establishes a baseline from historical utility data, then tracks real consumption post-completion. Reports show the measured difference in kWh and convert to CO₂ using BEIS factors - providing the evidence that retrofit programmes are delivering genuine savings.
What reporting do grant bodies require for public building energy projects?
Most grant bodies (PSDS, SHDF) require: pre-works baseline energy consumption, post-works measured consumption, calculated energy savings (kWh), carbon savings (kgCO₂ using government factors), and cost impact. HeatFlow generates all of these from measured data, with audit-ready methodology documentation.
Can HeatFlow track energy across different types of public buildings?
Yes. HeatFlow tracks any metered energy source - gas, heat, electricity, water - across any building type. Councils use it for social housing blocks, leisure centres, council offices, schools, and community buildings. All buildings are managed within a single portfolio view.
How does public building energy reporting support net zero targets?
HeatFlow tracks total portfolio carbon emissions over time, showing whether reduction programmes are keeping pace with declared net zero targets. Year-on-year comparison reports demonstrate progress, identify which buildings need attention, and provide the data for public reporting of climate action progress.
Is the data suitable for public scrutiny and FOI requests?
Yes. All data in HeatFlow is timestamped, source-tagged, and stored with full audit trails. Reports include methodology notes explaining how savings are calculated. The data is transparent and defensible - suitable for public scrutiny, audit committee review, and Freedom of Information requests.
